5 claims. (or. 215 -31 The present invention relates to bottles, and particularly to closures therefor.

An object of the invention is to provide a closure for bottles which is held in place by friction and may be put on and taken off the bottle by simple rectilinear motion.

A further object is to provide such a closure which has a smooth and uninterrupted interior and exterior surface so that it can be manufactured by a simple operation and can be kept clean in use.

A still further object is to provide means on the bottle neck for holding in place frictionally a cap having a smooth inner and outer surface and which, by means on the bottle neck, is deformable from its normal cross section to effect the desired frictional grip on the bottle neck.

Other objects and advantages of the invention will appear from the following description, taken in connection with the accompanying drawing, which illustrate, by way of example, a preferred embodiment of the invention, and in which:

Fig. 1 is a perspective view of a bottle neck constructed in accordance with the present invention and showing the cap removed;

Fig. 2 is an open end view of a cooperating cap;

Fig. 3 is a horizontal sectional view through the bottle of Fig. 1, to which the cap of Fig. 2

- has been applied;

Fig. 4 is an enlarged detail view showing distortion of the cap at the points of friction grip.

Referring in detail to the accompanying drawing, a bottle 11 is provided with a neck 12, which is smooth throughout except for one or more raised portions 13. These serve as frictional I grips for a cap, which may be made smooth inside and outside, and of the same shape as the bottle neck, which, in the illustrated embodiment, is shown as being cylindrical. The raised. frictional gripping portions 13 are in the present example of the invention shown as having the form of ridges extending axially of the bottle neck, but it will be obvious that their shape could be varied and that in cases where the raised portions have onedimension longer than another, the direction in which this dimension extends may be varied without changing their function, which is to effect a frictional grip on a cap having the same shape as the neck by engaging with the interior of the cap and slightly deforming it from its normal shape.

In the example of the invention shown in the drawing, a cylindrical cap 15, closed at one end and open at the other, is provided for cooperation with said neck and is made of any suitable make it possible to collect dust. -The raised portions on the exterior of the bottle neck are automatically formed by the very act of producing the bottle. The cap can be applied or removed by a simple axial motion and does not require any turning or twisting; nor does its removal require the dislodging of raised or indented portions from engagement with corresponding gripping portions on the bottle.

It will be obvious that various changes, particularly changes of size, shape, location and in some cases direction, may be made in the detailed construction described by way of illustration without departing from the invention as defined by the following claims.

What is claimed is:

1. A bottle provided with a neckwhich is externally provided with frictional cap gripping portions circumferentially spaced apart from each other for engagement with a cap having an unbroken smooth interior, said cap gripping portions deforming a cooperating cap radially outwardly at the cap gripping portions and radially inwardly therebetween.

2. A bottle provided with a neck which is externally provided with raised cap gripping and deforming portions circumferentially spaced apart from each other, said neck, except for said cap gripping and deforming portions, being externally smooth and cylindrical, and saidcap gripping and deforming portions being slidably engageable with the inside of a cap having an unbroken smooth interior while it is being applied to and removed from said neck, said cap gripping portions deforming a cooperating cap radially outwardly at the cap gripping portions and radially inwardly therebetween.

-3. A bottle having a neck provided with a cap closure, said closure being smooth externally and internally and normally of the same shape as said neck but larger in size, the neck of said bottle having means for deforming said closure from its normal shape and thereby frictionally holding said closure in deformed position on the bottle 4. A bottle having a neck provided with a cap closure, said closure being smooth externally and internally and normally of the same shape as said neckbut larger in size, the neck of said bottle having means for deforming said closure from its normal shape and thereby frictionally holding said closure in deformed position on the bottle neck while allowing said cap to be applied .to and removed from said neck with simple rectilinear motion in the direction of the axis of said neck, said means comprising a plurality of rigid ribs integral with said neck, spaced apart circumferentially of the neck and substantially parallel to the longitudinal axis of the neck, said ribs moving part of said closure radially outwardly and deforming other portions of the closure radially inwardly into the spaces between saidribs.

5. A container comprising a vessel having a mouth and provided with peripherally spaced retaining projections below the mouth, and a 010- sure comprising a top portion adapted to cover the mouth and a. resilient cylindrical skirt portion adapted to encompass said retaining projections and slidable axially of the vessel into and out of elastic gripping engagement with the outer surfaces of said projections.
